WIFlED GLASS.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed August 16, 1905. Serial No. 274,468.

To all whom t may concern:

Be it known that I, ROBERT A. B. WALSH, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain njew and useful Improvement in Wired Glass, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,hforming part of this specification, in

Figure 1 is a plan view of a glass sheet constructed in accordance with my invention, and Fig. 2 is a cross-sectional view through the glass sheet.

This invention relates to wired glass; and one of the objects thereof is to provide a sheet or plate of glass having embedded therein a plurality of wire meshes or fabrics which are so arranged as to better strengthen the glass sheet and protect the opening covered thereby in case of fire. l

Heretofore wired glass sheets have generally been provided with a sin le inesh, and in the event of excessive heat eing applied to the glass sheet, with thel resulting crackin of the glass, the tendency of the glass to fa away from themesh has been a serious disadvantage.

It is the prpose of my invention to so arra e the mesh that a continuous thick layer of g ass will be interposed between twoapproximate] flat parallel Wire meshes which are covere by'layers of glass having approximately smooth outer faces, said wire meshes being entirely embedded within theglass, so that in the event of excessive heat bein applied-as, for example, in the case o fire and in the event that the two outer layers of glass ,should break away from the meshes f rom any cause'the interposed layer or layers of glass will be held between the wire meshes, said inter osed layer being, continuous and comparatively thick, so that the door or op'en-l other practically the entire mgl in which the ca y be covered.

Referring now to the drawings by numerals of reference, the sheet of glass is illustrated as consisting of a continuous inner or intermediate layer of glass 1, separatin a plurality of wire fabrics 2 and 3. In t e present instance there are two shown but a greater number may be em loyed, if desired. These two fabrics are em edded in the sheet, so as to be covered by the outer layers 4 and 5. In actual practice the fabrics will be arranged in staggered relation to each other-that is to say, the meshes of one fabric will overlap those of the other fabric. By so arranging the meshes of the fabrics with respect to each body of the glass will be reinforced by the wire, so as to make the lass much stronger than the ordinary wire glass, and inasmuch as the wire fabrics act as binders or bonds the liability of the glass becoming pose the premises having an ered by said glass will be avoide Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A sheet of lass having embedded therein a plurality ofI parallel to. the outer faces of the sheetand glass is placed will practiwith their meshes overlapping each other,

said layers of fabric being spaced awayfroin each other and also from t e outer faces of the glass sheetlwhereby a continuous layer of glass of uniform thickness is interposed between bthe layers of Wirefabric substantially as described. i

In testimony whereof I hereunto aiix my signature, in' the presence of two witnesses, this 14th day of August, 1905.
